2. Scale (social sciences) - Wikipedia

   en.wikipedia.org/wiki/Scale_(social_sciences)

   For example, a scaling technique might involve estimating individuals' levels of extraversion, or the perceived quality of products. Certain methods of scaling permit estimation of magnitudes on a continuum, while other methods provide only for relative ordering of the entities. The level of measurement is the type of data that is measured.

3. Non-dimensionalization and scaling of the Navier–Stokes ...

   en.wikipedia.org/wiki/Non-dimensionalization_and...

   In fluid mechanics, non-dimensionalization of the Navier–Stokes equations is the conversion of the Navier–Stokes equation to a nondimensional form. This technique can ease the analysis of the problem at hand, and reduce the number of free parameters. Small or large sizes of certain dimensionless parameters indicate the importance of certain ...

4. Nondimensionalization - Wikipedia

   en.wikipedia.org/wiki/Nondimensionalization

   Measuring devices are practical examples of nondimensionalization occurring in everyday life. Measuring devices are calibrated relative to some known unit. Subsequent measurements are made relative to this standard. Then, the absolute value of the measurement is recovered by scaling with respect to the standard.

5. Multidimensional scaling - Wikipedia

   en.wikipedia.org/wiki/Multidimensional_scaling

   An extension of metric multidimensional scaling, in which the target space is an arbitrary smooth non-Euclidean space. In cases where the dissimilarities are distances on a surface and the target space is another surface, GMDS allows finding the minimum-distortion embedding of one surface into another. [5]

6. Semantic differential - Wikipedia

   en.wikipedia.org/wiki/Semantic_differential

   Respondents are asked to choose where their position lies, on a set of scales with polar adjectives (for example: "sweet - bitter", "fair - unfair", "warm - cold"). Compared to other measurement scaling techniques such as Likert scaling, the SD can be assumed to be relatively reliable, valid, and robust. [1] [2] [3]

7. Guttman scale - Wikipedia

   en.wikipedia.org/wiki/Guttman_scale

   In Guttman scaling is found the beginnings of item response theory which, in contrast to classical test theory, acknowledges that items in questionnaires do not all have the same level of difficulty. Non-deterministic (i.e., stochastic) models have been developed such as the Mokken scale and the Rasch model. Guttman scale has been generalized ...
